Kesler is her husband and is a Talentless who owns an apothecary called Slurps and Burps in Mysterium, which is designed to make all the 'stuffy nobles' squirm. They have been deemed a bad match. They are one of the most loving couples in the series and have a very deep trust and respect with/for one another. In addition, Juline does not lie to Kesler when she tells him where she is going, even if she does take a bit of a detour on the way to meet with the Black Swan. When he finds out that she is apart of the rebel group, he is unhappy at first but forgives her very quickly.

Dex is her oldest son who looks similar to his father and has a Special Ability, a Technopath. While in LodestarDex is upset with her for hiding the fact that she was apart of the Black Swan, he later forgives her. They are not necessarily shown to have an extremely close relationship, but it can be seen that Juline has respect for her son when Biana asks if she has her permission to give Dex a makeover, and Juline says that she'll leave it up to Dex. They do not seem to have as much trust with each other, as when she is revealed as Squall, Dex wonders if she took him to see Sophie to spy on her. She denies this, showing her care for him and insisting that instead she simply didn't want him eating in his alchemy lesson for a second year.

Daughter, one of the triplets, looks like Kesler and is a Level One. In one of the books, the triplets are seen running around Juline and messing with each other as she tries to get them to calm down. In Lodestar, Juline claims that she has a trick to control Bex and her two brothers, which Kesler tells Sophie she says every day. The trick does work, however, as Juline uses her frosterability to create snow, momentarily stopping Bex from running with Rex's stuffed jackalope. Not much is seen of Juline or the triplets, so it can be uneasy to confirm their relationship. But due to how Juline always seems rumpled and exhausted, it can be believed that she spends time with the triplets regularly.
